PATENT 0 JOSEPH M. MERROIV, OF MERROIV, CONNECTICUT.

METHGD OF OVERSEAIVHNG FABRICS.

SPECIFICATION forming part of Letters Patent N 0. 394,783, dated December 18, 1888.

Original application filed January 18, 1886, Serial No. 188,912.

To all whom it may concern Be it known that I, JOSEPH M. MERROW, of Merrow, in the county of Tolland and State of Connecticut, have invented certain new and useful Improvements in the Art of Overseaming Fabrics, of which the following is a specification.

My invention relates to a new method of finishing or overseaming the edge of fabrics, and is particularly adapted for use upon knitted and other elastic fabrics.

My object is to produce upon the edges of fabrics a finish which is ornamental and substantial, and which may be to a considerable degree regulated in elasticity by modifying the relative sizes of the threads or their tensions, or by adjustin the length of the stitches taken.

My invention consists in carrying a thread through a fabric near the edge thereof, drawing said thread from the point where itis carried therethrough on either side to the edge thereof, and there interlooping saidthread together with a supplemental thread forming a chain of loops or stitches from the two threads in terlooped together along the edge of said fabric by drawing said two threads through three loops or stitches at or near the edge of the fabric.

In the drawings, Figure 1 is a perspective view of a piece of fabric, showing the finish along a portion of its edge, also a needle and a crochethook. Fig. 2 is a view of the edge of a piece of fabric, showing a few loops upon its edge, also a needle and a crochet-hook. Fig. 3 is a perspective View of a piece of fabric, showin needle and crochet-hook.

Similar letters of reference represent similar parts throughout the drawings. I

A is the fabric.

a is the main thread or yarn, and a is a supplemental thread.

B is a chain of loops along the edge of the fabric.

0 is a latched crochet-hook, and I) is an eye-pointed needle.

In carrying out my invention the main thread a is carried through the fabric by any means adapted to the purpose. In the drawings the main thread a is shown as bcin drawn through the eye of a pointed needle, 1). Coin- Divided and this application filed December 2, 1887- Serial No. (No model.)

mencing at the position of said needle D, as shown in Fig. 1, said needle may be passed through the fabric A, carrying the main thread a to the position shown in Fig. 2. The crochet-hook 0, upon which are two loops of yarn, Z) and b, in Fig. 2, may be then advanced through the loop b at the side of the needle D below the fabric. From the position shown in Fig. 2 the needle D may be drawn back through the fabric A, carrying, the thread a with it, and the crochet-hook may be moved around the edge of the fabric, carrying the loops 1) I), which are shown upon the said crochet-hook in Fig. 2, together with the loop, b last taken from below the fabric. If new the crochet-hook G is carried forward so as to have its latch 0 carried through the loops Z) l) b and in a position to grasp both of the threads a a, and afterward said crochet-hook be drawn back through the loops I) Z) W, the latch 13 will be closed by said loops, and the latter will be shed oil from the crochet-hook C, and at the same time the two threads a a will together be drawn through said three loops, 1) 1) L as is shown in Fig. 1., and thus the edge of the fabric may be finished by a succession of such operations with a line of loops along the edge of the fabric represented by B. The two threads are shown here by different shades, and it may benoted that the relative prominence of the two threads along the edge of the fabric is somewhat changed by the relative tension upon the threads. lVith much less tension upon the supplemental thread a, said thread will have a tendency to become more prominent at the edge; but with considerable tension upon said thread a it will be less prominent. Any suitable means may be employed in carrying out my invention.

A machine adapted to the ,purpose forms the subject of my application for Letters Patent filed on January 18, 1386, Serial No. 188,912, of which my present; application is a division, and to which reference may be had for a more. perfect umlerstamling of this invention.

Having thus described my invention, I new claim-- 1. The art of overseaming or finishing the edge of a fabric, which consists in carrying a thread through the fabrie near the edge thereof, drawing loops of said thread from both sides of the fabric from the point at which said thread is carried therethrough to the edge, and forming loops thereon interlooped with loops of a second thread bydrawing loops of the supplemental and main threads through three loops previously formed from said supplemental and main threads, substantially as set forth.

2. The improvenn-zntin the art of eroeheting or overseaming, which consists in passing the main thread through the fabric near the edge thereof, grz'lsping said thread alternately on opposite sides of the fabric together with a supplemental thread on one side of said fabric, drawing the threads in the form of loops to or beyond the edge of the fabric, subsequently passing the main thread through the fabrie at a point suitably distant, formil'ig loops as before by grasping said main thread alternately on opposite sides and the supplemental thread on one side of the fabric, and drawing the loops thus formed toward the edge of the fabric, one loop of the main thread, together with the loop of the supplemental thread, being drawn through two of the preceding loops of the main thread and through the preeedin g loop of the supplemental thread, whereby the chain. of loops formed from the main thread is re-enlioreed along the edge of the fabric by the enehained supplemei'ital thread interlooped. with the main thread, substantially as set forth.

In testimony whereof I have signed my name to this s1 )eeilieation, in the presence of two subscribing Witnesses, this 29th day of l\'m'einl ier, A. D. 1887.

JOSEPH M. MERROXV.
